GUIDE FOR PAPER-MAKING MACHINES.

Application filed October 5, 1315.

To all whom it may concern:

Be it known that I, Anonzo ALDRICH, a citizen of the United States, residing at Beloit, in the county of Rock, State of iVisconsin, have made a certain new and useful Invention in Guides for Paper-Making Machines, of which the following is a specification.

This invention relates to guides for paper making machines.

The object of the invention is to provide guides for paper making machines which will insure proper feeding of the wet paper strips to the pressing rolls of the machine.

A further object of the invention is to allow adjustment in any direction of the guides.

A further obj eet of the invention is to provide guides of the class described which will. eliminate the possibility of injury to the operator of the paper making machine in feeding the wet paper strips to the pressing rolls.

Further objects of the invention will appear more fully hereinafter,

The invention consists substantially in the construction, combination, location and relative arrangement .of parts, all as will be more fully hereinafter set forth, as shown by the accompanying drawing, and finally pointed out in the appended claims.

Referring to the drawing,-Figure 1 is a view in side elevation of the press rolls of a paper making machine, and embodying my invention. Fig. 2 is a diagrammatic view showing the method of operation of the guide rolls.

The same part is designated by the same reference numeral wherever it occurs throughout the several views.

In the paper making machine art, it is the present practice to provide press rolls to press water or liquid out of the strip of paper or paper pulp and also to smooth the surface of the papen and to provide a frame for the press or smoothingrolls and means to actuate one of the rolls, the other roll bein actuated by friction contact therewith. In the present press or smoothing rolls, the paper strips must be fed between the rolls by hand, making the operation dangerous and uncertain.

It IS among the special purposes of my present invention to supply means to automatically feed the paper pulp between the Specification of Letters Patent.

press or smoothing rolls thereby insuring proper feed and eliminating the element of danger to the operator.

In the drawing, and referring particularly to Fig. 1 thereon, 1 designates the usual frame of the press or smoothing rolls comprising vertical standards as shown, and having brackets 2 forming the bearing for the lower press roll 3 which may be driven to rotate in the direction of the arrow, by any suitable means, such as by a belt, not shown. The upper free ends of the vertical frames 1 are provided with pivot pins 4, on which are pivotally mounted arms 5 carrying at their free ends brackets G which form the bearings for the upper )ress roll 7. The press or smoothing roll 'i is rotated in the ,direction indicated bv the arrow by frietional contact with the press roll 3. It is desirable to be able to adjust the roll 7 with respect to the roll 3, in order to relieve the pressure of the roll 7 upon the roll 3 and to prevent the flattening of the rolls covering when at rest. I show a simple arrangement for the accomplishment of this result wherein the frame is provided with a lug 8 directly beneath an extending portion 9 of the bracket 6 which is provided with an interiorly threaded hole therethrough. A rod 10 provided with screw threads as shown and adapted to screw through the hole in the portion 9 rests upon the lug 8. It is obvious that by turning the rod 10 in one direction or the other, the roll 7 may be moved nearer to or farther away from the roll 3, about its pivot at 4. To facilitate the manipulation of the rod 10, I provide a handle 11 keyed thereto as shown.

In accordance with my invention I employ what I term two tape feed rolls and a direction feed roll, each individually adjustable with respect to each other and with respect to the frame of the press or smoothing rolls, and all mounted on auxiliary frames adjustable with respect to the stationary frame.

I show one simple arrangement embodying my invention wherein the frame 1 is provided with vertical slots therein as at 12 through which pass studs or bolts 13. An auxiliary frame 1%, provided with horizontal slots 15 adapted to lie opposite the slots 12, is secured to the frame 1 by means of the bolts 13. By this arrangement, it will be seen that the auxiliary frame 14: may be 7 of the rolls 7, 22, 23, and 24, or all of the' rolls 22, 23, and 24, as a unit, may be moved shifted vertically or horizontally with respect to the frame 1, by loosening the bolts 13, and may be rigidly secured to the'frame 1 in any adjusted position by tightening said bolts. Similar bolts 16, 17 and 18, secure to the auxiliary frames 1%, bearing plates 19, 20,and 21, respectively, each of said bearing plates being slotted as shown to allow adjustment in any direction with respect to the auxiliary frames 14. The bearing plates 19 and 20 provide bearings for the tape rolls 22, 23, and the bearing plates 21, provide bearings for the direction feed roll 24. One of the tape rolls, such for instance, as tape roll 22, may be caused to rotate in the direction of rotation of the press or smoothing roll 3, by means of sheaves located on'each of said rolls, and a belt 25 connecting the sheaves. Wound around the tape rolls 22 and 23 are belts of tape, or other flexible belt material, as shown at 26.

It will be noticed that the direction feed roll 24 must be rotated in a direction opposite to the direction of rotation of the press or smoothing roll 3. This may be accomplished in any desired way, such as by direct belting with a sheave on the roll 7 or by cross belting as indicated at 29, Fig. 2, with a sheave on the driving press or smoothing roll 3. My invention, however, is not to be limited to these details.

From the foregoing it will be seen that the paper strips are thrown on the roll 7 as indicated at 28, in the usual manner. The roll being rotated in the direction of the arrow by frictional contact with roll 3 causes the paper strips to be carried over the roll 7, over the auxiliary guide feed roll 24, where it comes in contact with the tapes 26 of the tape rolls 22, 23, thereby insuring proper feed of the paper strips between the press or smoothing rolls 7, 3, and thereby eliminating the necessity of the attendant reaching behind the rolls 7, 3, and to insure the proper feed by hand.

As has been hereinbefore described, the' roll 3' is journaled in fixed bearings and each or adjusted relative to said roll 3 or to each other.

While I have shown and described one embodiment of my invention, it will be un derstood that many other arrangements embodying my invention will readily occur to those skilled in the art, and therefore my invention in its broad scope as defined in the claims is not to be limited or restricted to any detail or to the specificstructure shown.

Having now set forth the objects and nature of my invention, what I declare as new and useful, and of my own invention, and

. desire to secure by Letters Patent, is,
